A Study Of The Roles Played By The Trishanku Gene In The Morphogenesis Of Dictyostelium Discoideum
(2011-02-22)A hallmark feature of Dictyostelium development is the establishment and maintenance of precise cell-type proportions. In the case of D. discoideum, roughly 20% of the cells that aggregate form the stalk while the remaining ... -
Molecular Characterization Of The SLC22A18AS Gene From The Imprinted Human Chromosome Segment 11p15.5
(2011-02-21)The imprinting status of the SLC22A18AS gene, located in the human chromosome segment 11p15.5, was studied using PCR-SSCP analysis and fetal tissues from a battery of 17 abortuses. This gene showed monoallelic expression ... -
Epigenetic Regulators Of Development In The Social Amoeba Dictyostellium Discoideum : The Roles Played By Histone Deacetylases And Heat Shock Protein 90
(2011-01-20)The major evolutionary transition from single-celled to multicellular life is believed to have occurred independently of the main metazoan lineages in the cellular slime moulds, of which Dictyostelium discoideum is the ... -
Characterization Of Human Mammary Stem Cells Grown As Mammospheres
(2011-01-11)Adult stem cells are a small population present within several tissues of an individual, possessing two unique properties: one, the ability to differentiate to give rise to all the cell types of the tissue, and second, the ... -
Biochemical And Functional Characterization Of Evolutionarily Conserved Metallophosphoesterases The 239FB/AB Family
(2010-12-30)With the advent of large scale genome sequencing efforts along with more sophisticated methods of genetic mapping, a number of loci have been identified that are associated with human diseases. Intriguingly, many genes ... -
Aromatic Beta-Glucoside Utilization In Shigella Sonnei : Comparison With The Escherichia Coli Paradigm
(2010-12-01)The aromatic beta-glucosides of plant origin, salicin and arbutin, serve as carbon sources for the sustenance of bacteria when ‘preferred’ sugars are absent in the environment. In the family Enterobacteriaceae, there are ... -
Studies On Growth And Development Of The Ovarian Dominant Follicle In Monovulatory Species : Analysis Of Transcriptional Changes And Factors Influencing Periovulatory Events
(2010-10-28)In response to LH surge, the selected dominant follicle undergoes a series of complex events viz., meiotic maturation of the oocyte, terminal differentiation of follicular cells, cumulus expansion and follicular rupture ... -
Identification Of Domains Of The Follicle Stimulating Hormone Receptor Involved In Hormone Binding And Signal Transduction
(2010-10-08)The glycoprotein hormones, Luteinizing Hormone (LH), human Chorionic Gonadotropin (hCG), Follicle Stimulating Hormone (FSH) and Thyroid Stimulating Hormone (TSH) are heterodimeric proteins with an identical α-subunit ... -
Mapping Of Glycoprotein Hormone-Receptor Interactions Using Hormone Analogs And Antibodies
(2010-09-21)The glycoprotein hormone family comprising of Luteinizing Hormone (LH), Chorionic Gonadotropin (hCG), Follicle Stimulating Hormone (FSH) and Thyroid Stimulating Hormone (TSH) plays important role in reproduction and overall ... -
Human Spermatogenesis : Differential Gene Expression And Regulation
(2010-08-24)Spermatogenesis is a complex process of male germ cell development in which the diploid spermatogonia undergo series of mitotic divisions and differentiation steps culminating into the preleptotene spermatocytes which then ... -
Molecular Actions Of Arecoline, An Alkaloid Implicated In The Manifestation Of Oral Submucous Fibrosis (OSMF)
(2010-07-21)The pathogenesis of oral submucous fibrosis (OSMF) is due to a complex interplay between the production and degradation of extracellular matrix (ECM) protein components. In tissue fibrosis, there is a net accumulation of ... -
Studies On The Expression Of The bgl Operon Of Escherichia Coli In Stationary Phase
(2010-03-19)The bgl operon of Escherichia coli, involved in the uptake and utilization of aromatic β-glucosides salicin and arbutin, is maintained in a silent state in the wild type organism by the presence of structural elements in ... -
Evolution Of New Metabolic Functions By Mutations In Pre-Existing Genes : The chb Operon Of Escherichia Coli As A Paradigm
(2009-07-02)Escherichia coli has the ability to respond to stress such as starvation in a very efficient manner. Under conditions of starvation wherein a novel substrate is provided as a sole nutritional source, Spontaneous mutants ... -
Expression Profiling Of Genes Regulated By TGF-β : Role Of Multiple Signaling Pathways
(2009-05-12)Transforming growth factor-β (TGF-β) is the proto-type member of a super family of secreted proteins comprised of several structurally related, but functionally divergent proteins like the BMP, activin, inhibin, mullerian ... -
Receptor Guanylyl Cyclase C Cross-talk With Tyrosine Kinases And The Adaptor Protein, Crk
(2009-03-06)Signal transduction is a crucial event that enables cells to sense and respond to cues from their immediate environment. Guanylyl cyclase C (GC-C) is a member of the family of receptor guanylyl cyclases. GC-C is a single ... -
Gene Expression Profiling And Insights Into The Involvement Of The Insulin Signaling Pathway In Oral Cancer
